Question

我正在使用Bootstrap v3.3.6和jQuery v2.1.1。我想问为什么我的navbar没有在nav collapse的决议中转到sm？在width: 768px分辨率下，nav collapse出现。但在width: 768px，它没有。

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<nav class="navbar navbar-default navbar-inverse navbar-fixed-top">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">
        <img src="img/logo.png">
      </a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="people.html">People</a>
        </li>
        <li class="active"><a href="index.html">Gallery</a>
        </li>
        <li><a href="inspiration.html">Inspiration</a>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li><a href="listJob.html">Jobs oportunity</a>
        </li>
        <li><a href="">hirring a chief?</a>
        </li>
        <li><a href="signUp.html">login|signup</a>
        </li>
      </ul>
    </div>
    <!-- /.navbar-collapse -->
  </div>
  <!-- /.container-fluid -->
</nav>

请告诉我如何让nav collapse显示在min-width: 768px？

Bootstrap Media Query默认为少于768px（不包括）

/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */

这就是为什么它的工作频率低于768px而不包括。

sm媒体查询包括768px及以上。

/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm-min) { ... }

您可以添加自己的媒体查询以包含768px

@media screen and (max-width: 768px) { ... }

Navbar折叠不会显示在768px
